@Nikaple Hi, one more thing regarding default values. I'm planning to update the docs a bit over the weekend, and I think that will be fine.

I have one more feature in mind but it will be for a bit later.

Right now, we make the resolution and, after that, do merge, but ideally, we should do merge first and then resolution it will be more accurate behavior, and performance will also be better, for my use cases at least.

I'm implementing a kind of PROFILES in spring

@Nikaple Hi, any concerns merging this?

[Nikaple]

Certainly, I find the code to be fine. As per our previous conversation, you mentioned your intention to make some adjustments to the documentation during the weekend. I am still waiting for the updated version 😆
